HAMMEL KompBio

The HAMMEL KompBio is a multi talent. Different machines are united in one: primary shredder screen secondary shredder The HAMMEL KompBio works in several steps. In the first step the feeding material, for example: biomass fresh wood root stems tree stems compost wet wood waste wood is pre-shredded, afterwards it drops on the integrated disc screen, where organic and mineral parts are separated and discharged. The here generated end product is suitable for composting. The clean, pre-shredded wood is then carried to the secondary shredding step. Exchangeable screen baskets and the design of the secondary unit guarantee an exact and regular end product with almost 100% constant chip size according to further usage of the crushed material (composting or energy utilization). The secondary shredder, integrated in the HAMMEL KompBio, produces chips with a size of approx. 40 mm to 100 mm (depending on the size of the screen basket). Alternatively, the HAMMEL KompBio could be used as a windrow turner. For this purpose the screen basket of the secondary shredder is kept open during the shredding process. In case the material contains metal parts, the HAMMEL KompBio can be optionally equipped with a magnet. By the way, our multi talent does not only shred wood but also a multitude of other materials.

HAMMEL KompbiStar

Applications The high-speed shredder has been specially designed for material, such as: fresh wood green waste branches and bushes up to 300 mm diameter forest residue bark waste wood Material feed The raw material is loaded directly into the automatically operated feed hopper and goes through the feed roller into the shredding rotor. This principle guarantees continuous and permanent material feeding. If the material is too dense, the feed belt revs are automatically regulated and adjusted to suit the material, to prevent blockages in the rotor. The rotor is equipped with bolt-on hammers, which are easy and quick to change. They produce an end product of less than 50 mm*.

HAMMEL-shredder

The HAMMEL-shredder is a reliable working equipment, because of its robust and clear construction. The use of high-grade steel and the installation of quality products offers you the well-known HAMMEL-standard. We put technical innovations directly into practice and guarantee in this way highest quality and the latest standard. All HAMMEL-shredders are typical for: high performance minimum dust generation low wear and tear very low noise no projectiles no fire hazard

Secondary Shredder

Drive Diesel hydraulic drive with Caterpillar-engines or alternatively with electric hydraulic drive. Operating via switch box and through an upstreamed plant. The secondary shredder has a direct connection to the primary shredder, therefore a priority switch off in case of interferences is possible. Permanent over-belt magnet The magnet is installed in line over the discharge point of the output belt. Metal parts are discharged in moving direction to achieve the best possible metal separation. The measurement of the magnets depend on application size. Options different electric or permanent magnets Automatic metal separation The automatic metal separation consists of a metal detector and a discharge flap. It recognizes ferrous and non-ferrous metal parts in the material. The metal detector is adjustable to variable sensitivity. It is positioned at the feeding belt and controls a discharge flap, which is situated at the end of the belt or before the secondary shredder. Rotor and screen operation The rotor diameter is about 700 mm or 1.000 mm according to the version. The rotor’s working width and the number of fixed knives depend on the type. The screen basket is hydraulically capable and equipped with overload protection. The mesh sizes of the screen basket can be chosen according to the required end product size. Material discharge The discharge belt is approx. 1.000 mm wide and has a discharge height of approx. 3.400 mm – 4.300 mm. A magnet roll is build at the end of the belt to separate the uncovered small metal parts like nails, screws etc. from the final material. Options belt cover hydraulically adjustable belt height Additional equipment water sprinkling system noise absorbing package Type HAMMERMILL Normally we use for our Secondary Shredder a rotor with fixed knives. However it is possible to choose the shredding unit as a HAMMERMILL with swinging hammers. Advantages for a rotor with fixed knives very high performance, extremly low energy consumption, quick and easy maintenance of the tools, low wear costs, equal end product, reduced sawdust Advantages for the HAMMERMILL with swinging hammers longer service intervals, insensitive to foreign bodies, massive hammers
